michael@0 9 * SUMMARY: Testing script with at least 64K of different string literals
michael@0 10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
michael@0 11 *
michael@0 12 * Testing that script engine can handle scripts with at least 64K of different
michael@0 13 * string literals. The following will evaluate, via eval(), a script like this:
michael@0 14 *
michael@0 15 * f('0')
michael@0 16 * f('1')
michael@0 17 * ...
michael@0 18 * f('N - 1')
michael@0 19 *
michael@0 20 * where N is 0xFFFE
michael@0 21 *
